To all whom t may concern l Be it known that I, CLIFFORD H. RAMSEY, acitizen of the United States, residing "at Paterson, in the county ofPassaic and State of New Jersey, have invented certain new and usefulimprovements in Hydro-Extractors, of which the following isa specifica`tion of such bearings is effected in a way cal-l culated to keep exposedsurfaces of the machine free of lubricant andto confine the lubricantagainst being thrown off by the rotating element onto the contents oflthe basket or receiver part of the latter.

In the accompanying drawings, in which i the invention -is fullyillustrated, Figure-l is a vertical sectional view of a hydro-extractorcontaining my improvements; Fig. 2 is a vertical sectional view, on alarger scale, of parts including immediately the upper bearing; Figs. 3and 4 are horizontal sectional views on the lines :z2-a' and 3/-1/ ofFig. 2; and, Fig. 5 is a side elevation of the rotating bearing part orbushing.

a, is a li uid receptacle having a drain outlet b its bottomelevated'centrally, as at c; and d is aframe arranged upon thereceptacle a. f

e is a vertical shaft which carries the basket 0r other reticulatedreceiver f for the fabrics or the like from which the liquid is to beextracted centrifugally.V A step bearing is afforded for this shaft by asocket g suitably secured ina hole z. formed centrally in the bottom ofthe receptacle ai and by the sleeve i secured in and concenf trically ofthe socket g and in spaced relation thereto and containing a bushing j,

. said sleeve and bushing being radially perforated, as at lc.

The upper bearing for shaft e, vertlcally above the step bearing, isarranged in the arch d of frame Z and is constructed as follows: Asleeve Z having a reduced lower end m is secured by screws n penetratinga lia-nge 0 at its upper end in a vert-ical holeformed in the arch d ofthe frame.' Into thls sleeve, which has threading on the inside at itsupper end, is screwed a bushing or bear mg part Q, which on the insideis conical, the taper belng in the upward direction; at its upper end.it has a flange provided with spanner holes r. Whenthe bushing g hasbeen adjusted up or down, it may be held agalnst turning by a lock nutshaving spanner holes t.'

Screwed into the lower reduced end of the sleeve Z and standing uprighttherein is a .thimble u, which forms with the sleeve, an

annular lubricant well, the top ofthe thimble belng appreciably belowthat of the sleeve. v

The shaft e has secured thereon, as by the key t', an exteriorly conicalbushing or bearing part fw, the taper of which is upward. As shown, saidbushing is secured at its upper portion to the shaft, and its lowerportion depends into the well formed' by conical surfaces of thebushings g and fw, as shown in the drawings the bushing w, has formed inits conical surface reverse spiral `grooves a'. Once the shaft has beenstepped in the step bearing with its bushing fw contained in sleeve Z sothat its lower portion depends into the well formed by said sleeve andthimble, bushing g is introduced and screwed down until it isinceperating relation, to form a journal, with bushing w, whereupon thelock nut s is set.

' The shaft has an axial lubricant passage y extending therethrough fromend to end. In this passage is 'a constant level lubricant retarderconsisting in the present case of a plug .e fixed in the passage andhaving its upper end reduced and a vertical bore 2 eX- i tendingupwardly from its lower end into its upper reduced end and furtherhaving lateral openings 3 leading from said bore to the exterior of itsreduced end. From a point below the level of the openings 3 but oppositethe reduced portion of the plug a an inclined port 4 extends frompassage y through the shaft and bushing fw to the eX- terior ofthelatter, the outer end of said port being slightly above the lubricantlevel of the retarder indicated in Fig. 2 at 5.

Keyed to theshaft e below thesleeve Z is a catch-well 6 into which thereduced portion fm, of said sleeve depends, the catch-well preferablyhaving an inwardly projecting lip or flange 7 surrounding said reducedportion m. Leading from the well 6 inwardly Patented Jan. 2, 191'?.

sleeve'Z and thimble u. One or other of the at an incline a hole 8 isformed in the shaft e, and in Ithis hole is fitted a tubular spout ornozzle 9 whose inner 'end is substantially exactly in the axial line ofthe shaft. The

lubricant, as oil, is fed to the upper end of the passage y from a cup10 having a delivery tube 11.-

' The rotary member including the shaft e and basket f may be rotated byany suitable means. In the present instance the power is derived from almotor 12 and transmitted through a sprocket and chain connection 13 eto a4 horizontal shaft 14 journaled in frame d and carrying a conicalface plate 15 bearin against a cone 16 fitted on shaft e.

he lubricant being allowed to drip from .the cup 10 and pipe 11 into theshaft it first fills up to the level 5 at the 'retarder z and thenoverflows andfalls into thestep bearing, which intime becomes filledLwith oil, the overflow from the step bearing'passing out at the drainoutlet with the liquid thrown of from the basket. So long as thel rotarystructure e-f is not 'rotating no oil is delivered to the upperbearing.. But during rotation, centrifugal force' impels oil checked bythe retarder a to flow up the inclined port 4, so. that it comes'between the Y `the constant level retarder s which keeps a certainquantity of oil in reserve ready to be delivered to the upper fbearingupon the machine being started and at the same time allows any surplusdue t0 the oil being' left to drip from the oil cup While the machine isstopped for short period to overflow and vescape to the lower bearing;flooding of the upper bearing with oil is a serious objection inmachines vof this character, because when there is a superiluity of oilit is likely t0 Work out of any means for confining it onto other partsof the machine to ultimately fall -on the contents of the basket orbethrown by centrifugal action directly upon them. In the presentconstruction the oil, as will be obvious, is delivered to the upper,bearing only when it is required.

Oil admittedto the lower bearing enters at the bottom and is dischargedat the top, above the level of the water .draining olf through theoutlet b, whereby the water isv notonly kept from the rotating-.shaftbut from the lowerbearing, and said-bearing always has the benefit ofonly oil circulating through it.

The overflow from well L-u falling into catch-well 6 is drained from thelatter by l level lu spout 9 when the machine is stopped, the i oil inthe catch-well never accumulating to such an extent during a runningperiod as to be thrown out past flange 7 by centrifugal force. -'1 `oprevent the more or less copious flow of oil down passage y from beingdriven by centrifugal force up the drain outlet from. the 'catch wellinto the vlatter I have provlded the spout 9; so long as this spoutprojects beyond the surface of the passage mto the same it accomplishesthe purpose, but 1t is 'best to have it project so far that .its endwill be at the point where the centrifugal force is. m'Z-to the axis lofthe pas- Sa. x v o -aving thus fully "described myA invenl tion, rwhatIclaim .as new and desire to secure by LettersPatent is v 1.
